Advice on best upgrade path for a Mac Mini setup


Hi all,

My beloved PWT transport was shipped out for service last week, so in the mean time I decided to experiment with the Mac Mini which usually resides in my 2nd system. It was no surprise that it doesn't even come close to the PWT, but it sounds OK, and now i'm curious as of what I can achieve with it without spending another $2K.

It's a stock Mac Mini about 2 years old with an SSD drive.
I'm using it to stream TIDAL Hi-Fi.
I have it hooked up to a Schiit Wyrd USB re-generator via a Pangea silver USB 2 cable, which in turn is feeding my DSD via a WireWorld Starlight 7 USB 2 cable.
My thinking was that the Mac-to-Schiit path will be less critical in terms of cables, as it gets regenerated anyway, but I'm open to listen and learn...
That "Wyrd Schiit" re-generator did make quite a noticeable positive impact when I hooked it up in my 2nd system.

My question is - what will be the best bang-for-the-buck upgrades? 

I guess the switching power supply is a weak link so I looked at Mojo Audio stuff and those prices seem unreasonable - they want more for their power supply than what I paid for my PWT (including its superb power supply).
Any other recommended power supply upgrade kits?
I'm good with DIY and can probably do the upgrade myself.

Perhaps go with much better cables? Better isolation? Better re-generator?
What did you guys try that proved to really do the "magic" for similar setups?
Perhaps it is a 'losing battle' and it will never sound nearly as good as my PWT without spending $2K in upgrades?

Thanks for your advice!

@ryriken66  To switch to A+ without iTunes, you don't need to download anything else. There is a mention option to toggle. The mode using iTunes is called INTEGRATED. You just need to toggle that off. If you don't like their database, you can just as easily toggle back.
Word of caution, many switch then complain about loss of artwork. That's because music ripped/dowloaded via iTunes doesn't imbed art in each track, it keeps it in a separate file. This format is different than A+ and most other software, so you have to add artwork to each song's file if it's missing. Search archives for Dougscripts and/or Yate tag editor for help fixing missing art. Cheers,

This stuff is discussed in gory detail daily on a computer audiophile related forum that you should all read before recommending ten year old computing solutions. This stuff has changed too fast!

Guilty as charged. Excuses stifled. Heck, in my eagerness to share I sometimes fail to read (or reread) the whole thread. :)
In dbtom’s defense, his comments were on the mark relative to the OP’s inquiry.

(not that he needs my defense)
@sbank do you output the Sonore to a DAC? Looks like the output is USB only. I had my DAC, Yamamoto YDA-1, before I had a streamer so needed something with an RCA spdif output. I've added the Sbooster power supply to the Aries, $370 from Acoustic Sounds. That combo Sbooster/Aries/Yammie DAC sounds great to me and just as importantly has been glitch free.
@jond Yes, I have the microRendu USB output connected directly to the USB input on the back of my Schiit Gungnir Multibit, with the hard adapter that is included with purchase. You can see pic on my system page. It's smaller than a deck of cards. 
Heard good things about Sbooster psu, but haven't heard it myself. Cheers,
